Artificial photosynthetic starch from liquid sunshine

Sunshine and the cardiovascular benefits – a dose of sunshine!

The preservation of erythrocytes at liquid nitrogen temperatures with hydroxyethyl starch: the removal of hydroxyethyl starch from erythrocytes after thawing.

Hydroxyethyl starch (HES) has been shown to protect erythrocytes from freeze-thaw damage when these cells are frozen rapidly in liquid nitrogen and stored in the vapor phase at 145” C (8, 14). This alkylated starch is a product of the reaction of ethylene oxide and amylopect,in (7). The viscosity and molecular weight of the material is adjusted by acid hydrolysis. The product used in this study...

Sunshine on MS

tion, and thought that visual solar radiation might provide protection from developing MS. In 1970, a study from Switzerland (which is on a similar latitude in the northern hemisphere as Tasmania is in the southern hemisphere) [5] showed a higher clinical RR in winter and spring months, and a later study (also from the northern hemisphere) [6] of seasonal fluctuations in Gd-enhancing lesions on...

Sunshine or Shield?

How does the use of a secret vote affect the likelihood that legislators will punish their peers? Two contending arguments exist in the literature: some argue that secret voting may be prejudicial, while others argue that it may help accountability. We address this controversy by analyzing the case of the Brazilian Congress, which uses a sequential combination of open and secret voting procedur...

Fermentative hydrogen production from glucose and starch using pure strains and artificial co-cultures ofClostridium spp.

BACKGROUND Pure bacterial strains give better yields when producing H2 than mixed, natural communities. However the main drawback with the pure cultures is the need to perform the fermentations under sterile conditions. Therefore, H2 production using artificial co-cultures, composed of well characterized strains, is one of the directions currently undertaken in the field of biohydrogen research...
